Not in this case, but generally:
I rely on the sequencing of lists, since I rely on a order to events
on the iteration of elements. Shuffle my list, and I break.
I do tend to think of a list as a sequence, not a collection.

But assuming your case holds firmly, why are we filtering the
significance of ordering - if that is the distinction - throught the
words homogenous and hetereogenous. Why do we not speck directly
about the signficance of ordering. In the interest of least action.
